Warning, Construction & Information SignsStandalone practice
You see this yellow sign on a mountain highway. What should you do?

Correct answer: Check your speed and brakes, and be ready to shift to a lower gear.
Why
On a long downgrade, riding the brakes can overheat them until they stop working well. A lower gear lets the engine help slow the vehicle. Montana law forbids coasting downhill in neutral or with the clutch pressed in.
